Answer: Bella is correct.
Explanation:
Let the number of weeks will it take her to save enough to buy her coveted bike be represented by w.
The information given in the question can then be formed into an equation as:
45 + 11(w) = 265
45 + 11w = 265
Collect like terms
11w = 265 - 45
11w = 220
w = 220/11
w = 20
He'll save for 20 weeks
